Methane Release -- Oh, Dear

Not quite like clockwork. Yes, there will be a new Mew Madrid quake but no one knows exactly when. Also the supervolcanoe beneath Yellowstone Park will blow, but no one knows exactly when.

Not able to pin it down, back in the 70s we had people calling for an ice age based on five years of declining heat. and almost any period if continued would bake or freeze, but they do not continue.

My best guess based off of the last two, 23,000 years ago was much warmer, all the ice melted, sea level seven meters higher. A tropical England, Hippos, crocs, lush vegatation, and temperate forests in Scandinavia. Out past the Urals, people lived above the Arctic Circle, along the coast. Maybe just for the six months of day.

This end of my prediction calls for the same to happen again, in a thousand years.

The ice age before that, 32,000 years ago, it was very much like now. Northern ice covered ground exposed, Arctic Ocean becoming ice free, but with some very cold winters.

I agree that the Gulf Stream gets disrupted by fresh water floating on top of the Arctic Ocean, flowing south and staying on the surface, disrupting the flow. Cold brine would sink.

Fresh water has lower limits than brine, if warmed, it evaporates faster, if chilled it freezes sooner. Brine can get colder than ice, and absorb heat better. without evaporating.

So after the fresh water runs off, pushed up and out by the denser brine, the current conditions, warm and warming Arctic, are suddenly replaced with a much colder brine on the surface. This leads to a much colder winter, with the ground being ice and snow free, dryer Arctic, which allows the mud and rock to get very cold, deep cold.

When the warm and moist air following the Gulf Stream flows over this Cold Plate, it cools, and drops it's moisture as rain, then sleet, snow, and becomes smaller and dryer, a low pressure area, and faster moving, drawing in more behind.

Once the Ocean to cold land conveyer starts, it continues till it has deposited fifty to seventy kilometers of snow, which compacts to five to seven kilometers of ice, and then flows outward.

The last lowered sea level 150 meters 450 foot, Till the ocean was cold, very salty, and would no longer evaporate.

I think the trigger will be when the surface of the Arctic Ocean turns to brine, and current melting is keeping a fresh layer. The ice age before had a longer time for the fresh to run off, 10,000 years, But until recently, we had an ice covered Arctic, so I would guess a thousand years till the brine rises, and turns the north suddenly cold.

We seem to be having a wet Arctic, more water vapor, which has been delivering increased snowfall. Very early this year. More fresh water that will flow toward the Arctic.

When all the fresh is mixed with the oceans, or as vapor in the air, The Arctic is cold, salty, and all of the land around is ice free, run south as fast as you can.

New Madrid last went off in 1811, we have no records from 1611, but the Geologic Record, mashed rocks, does point to a consistant interval, 200 years, and big, a Nine.

It is not an if, it is a when.

Interesting!....What is brine...how does it play a role in global cooling?

Brine is salt water, denser than fresh, which can absorb more heat without evaporating, and get colder than ice. All ice is fresh water.

When water evaporates, changes from liquid to vapor, it takes up heat, some 500 calories per gram. Warmed moist air produces wind, transports the water.

When this Heat Engine reaches an end of the cycle, like Arctic brine absorbing heat without evaporating, being colder than ice, and the world oceans being warm, and creating even warmer air by evaporation, the winds pick up, driving the warm moist air over the cold plate, where contracting, they speed up and draw in more behind.

This produces the rare Circum Polar storm, The Japanese Current, the Gulf Stream, feeding warm moist air to the north, that goes around the Pole, reaching 300 miles an hour, and runs till it uses up the heat/moisture, a thousand years or more.

There is much evidence, around the Pole is scoured earth, where the wind took everything loose,. In other places the short stumps of large forests, snapped off at ground level and blown away, and islands with piles of trees, bones, smashed, packed on the windward side. Some caves facing into the wind are packed with shreadded organic matter. In Alaska, the deposit is called The Muck, forests, animal, stones, dirt, packed in deep deposits left when the wind dumped it's load.

After it was shreadded, animals in their skin with every bone shattered, it was flash frozen.

The Arctic Ocean became and stayed frozen, till now, The organics are just now decaying, releasing Methane.

The garbage pile that spent the winter frozen is now smelling like Spring.

This is the way ice ages start, Methane from the Arctic puts Carbon to shame as a greenhouse gas, it is going to get warm.

Then in a thousand years, our fifth thousand year storm in the last 33,000 years.

The only odd period in our climate history has been the last 500 years, mild, consistant, crop after crop, nothing like it in history.

900 to 1300 was the little ice age, ice year round in northern Scotland, in 705 the Black Sea and the Nile froze. Before that are reports of growing grapes in Greenland. In 400 the Romans wrote of the wines of Scotland, a major export. The England they occupied for 400 years was a warm and sunny place.

8000 years ago all of North Africa was grassland, trees, lakes, streams, from the Atlantic to Iraq and Turkey. Very suddenly it turned into the Sahara, and has continued. Before that for hundreds of thousands of years it was rich and green.

from 14,000 to 12,500 years ago was The Lesser Dryas, a fifteen hundred year worldwide dust storm. When it settled, it left fifteen to thirty meters of sand, grit, dust, over most of the north, the Losse, the windblown soils.

No one saw the stars for fifteen hundred years, the sky was brown.

I have studied these wonders, and got stuck living in the one most boring of all periods.

You live during an era of astronomical progress that has not been previously matched in the entire history of the human race. Also if you get far enough out of town you can see the stars with your own eyes.

Space travel is exciting, but if it's only so that we can kill another planet, what's the point?

That planet is doomed regardless of who is there. Nothing in the cosmos lasts forever.

the astronomical progress seems as if it is rushing us to our own self destruction. The natural earth is far more interesting.

Underwater exploration has never been as active as it is now. That applies to 70 percent of the surface of the planet.

Also manned expeditions to the deep have a lot in common with manned space exploration. Both are in an environment that is totally alien to us biologically. We depend absolutely on the vehicles and the stores they carry.
